Johannesburg - A motorist has been caught doing 257km/h on the N1 north, Johannesburg metro police say.
It was the highest speed reading for a motorist captured by police instruments in South Africa, spokesperson Wayne Minnaar said on Monday.
The motorist, driving a silver Audi TT, was one of seven speedsters trapped between the Grasmere toll gate and the Golden highway on Sunday night and Monday morning.
A red BMW was caught doing 197km/h; a silver Volvo S40 at
183km/h; a blue Toyota Corolla at 186km/h; a blue BMW 320 at
219km/h; another blue BMW at 198km/h and a silver Toyota Corolla was stopped doing 194km/h.
The previous highest reading was when police caught a red Lamborghini doing 251km/h on the N14 a few weeks ago.
All drivers were arrested and granted bail of R1 000.
They will appear in Johannesburg Magistrate's Court this week.
